Legal Question in Real Estate Law in Washington

Re: property

If you use community property (eg your salary) to pay for the expenses of the house, your spouse likely has gained a financial interest in the house. The precise amount of his interest cannot be determined from the information given.

However, the interest likely is not 1/3 of the property, especially since your marriage is only "a little over a year".

If prior to marriage you two lived together, he may have gained some interest in the house through the doctrine of committed intimate relationship (formerly meretricious relationship).

Even if you use no community property to pay for the expenses of the house, in WA, the court in a dissolution of marriage proceeding has the authority to divide all assets and debts whether community or separate in a just and equitable manner.

You may want to review with an attorney your facts and options (especially if divorce is in the horizon).
